', Thisspeciiication, aided by the accompanying drawing, discloses certain improvements rin container valves.rv Y

f In that special branch of commercial production and vdistribution certain containers, collapsibleL tubes and the like are employed tol vend Aplastic materials such as tooth-paste, vaseline,

andvarious other materials including medicinals having a paste-like consistency, and the practical j 10 means employed to discharge a requisite quantity 1" of the contents` oi the container tube is by means .rofsqueezingfa portion of the container tube to a compressed condition, thereby dispelling the neededA quantity through the aperturel provided 15 within',thefprojecting neck formed on ,the conwtainer tube. AThe discharge aperture, of the container tubes, most numerous in use, is opened and ,..clo'sed by means of a screw-threaded cap removfably attached 4to the screw-threaded surface `formedupon the apertured neck. The screwthreaded type oi removable caps has many objectionable characteristics, not only because of fthe possibility of the cap being dropped upon the ioor whilebeing unscrewed thereby encountera Ving a possible loss of thecap, but also because of the fact that the screw-threading of the cap and the tube is an appreciably expensive process to be expended on an article discarded as so lmuch scrap material when its contents have been consumed. y l

The container Valve herein described and illustrated is primarily directed to overcome, not only the .objectionable characteristics `of the screwthreaded type of construction, but also to provide a container valve appreciably more economical tomanufacture and as an article of manufacture constituting a' complete assembly unit. n Briey summarized, the herein described and illustrated improvements provide:

A container Valve simple in construction and operation. f

A container valve having few parts and therefore of minimum production cost.

A container valve designed and constructed for production by means of a die-forming process.

A container valve openable by manually drawing the cap in one direction and then swinging v Y the cap laterally to expose the discharge aperture.

A container valve capable of being securely lockedin a closed position.

A container valve non-leakable.

A container valve that' will resist leakageunder pressure. v

Y

A disc shaped cap I9 is also a member part of this construction and has provided upon one of its faces a projecting portion 20 dimensioned to t snugly into the tubular body at the designated open end thereof 2 I Upon a face opposite to that of the projecting portion 20`is an elevation 22 and within which elevation Va counter-sunk chan-V nel 23 is provided. Adjacent the channel 23 and in alignment therewith apertures 24 and 25 are provided marginally spaced within the larger Idiameter of the disc cap- I9, and the circumferential contour of the enlarged diameter at 26 isV knurled to accommodate manipulation.

Included in this construction of container valve is an angularly formed metal .strip 21 having aV straight vilat portion 28 Withangularly bent portions 29 and 30 providing depending prongs. Marginally spaced from the .extreme end of .the prongs 29 and Snare cut-out forms providing notches 3| and 32 leaving a narrow stay portion of metal 33V and 34 the marginal ends 35 and 36 of which are semi-circular 'in form. The angularly formed metal strip '.21 'thus .formed is arranged in assembly with the disc cap 'I9. The metal strip is then assembled upon the'cap I9 with prong portions 29 and 30 entered Sinto the apertures 24 and .25 .and pressed to a position in whichv the flat straight portion 28 of the metal strip 21 rests seatedly within the channel 23. This arrangement suggests firstly.; .the bending of the stay portions '33 and 34 in a rectangular form in parallel relation with the straight flat Y surface portion V28. Thercap assembly is then positioned on the shell-.formed tubular 'body I2. The rectangularly bent stay vportions 33 and 34 are sprung over the depending portions lI and vI6 and entered into the arcuately .radial .openings Yof the inverted T-formed slots II and i8. The

cap assembly is then swung to a position to permit the insertion of the projecting portion 20 to be entered into the tubular opening 21., .andlwhile in this assembled condition the stay portions33 and 34 are again bent in an axially .lengthwise direction with respect to the longitudinal .axis of the tubular body I2, thus providing a complete assembly unit container cap.

The unit thusformed is then 'attached to a lcontainer or collapsible tube `II'I ,Vandv this is accom-YV plished bypressing the tubular body II2 .into theY aperture provided within .the neck .I-I of the container, includingcollaps'ible tubes. I'he tubular body I 2. is dimensioned. measurably greater in length than the length of' the neck II Y.of the tube, and this excess length of the tubular body is then spun over., by means of a spinning tool, thereby forming a turned over anged end 39 whereby .the entire Valve assembly unit is fixed ysecurelyto the container or collapsible tube.

The container valve thus arranged is operable manually by drawing the capupwardly from off its seat to a position approximately to that indicated in dotted outline Fig. 1'; the cap is then swung latterly (indicated in `dotted outline Fig. 1)

within the radius R so that the discharge aperture Y2| of the container is completely uncovered and free to discharge the lcontents unobstructedly It is obvious that the closing .of the discharge aperture is Vonly the reverse `of .the opening process.

Y The successful operation of this container valve is the result of its novel features of construction combined with the co-operative functioning of its several parts. The form of the openings providing the slots Il and I8 within the depending portions I5 and I6 forms that which'may be defined as a guide-Way for the engaging bent ends of the prongs 33 and 34. VProvision isj also made by means of which the cap-I9 can be locked securely while in a closed position on the container. The bent notched ends of the prongs have slidable bearings within Vthe axially lengthwise slots I1 and I8. extreme end a bearing Within which the bent over ends of the prongs have pivots provided by the ends 3l and 32 of the prongs. i ends 35, 3S are semi-circular in form and their Yend surfaces provide a stop limiting the upward .slidable movement of the cap at the instanceY of their contacting with the under surface I3Yof the anged end of the tubularbody I2.

Referring tol Fig. l0, ofthe drawing, operational features of the end bearingslof the depending `prongs are outlined. Observing that when the cap ispelevated to -a position indicated inl dotted outline Fig. l, the stay portions 33 and 34 are in Va position to pivot in the guide-way slot I1 (the vpivotable position of the prongs 29, 30 being indicated in dotted outline), and inwhich position thecap i9 would beV moved within the sweep of the dotted outline radius R Fig. 1. At the in- Astant vthe cap is closed or seated, With the projection thereof Yllwithin the aperture 2 I, the cap is susceptible of Ybeing swervedV or turned arcuately in a right hand or left hand direction about 5 and 10. degrees, the result of such movement is to bring the stay bearing, portions 33 and 34 into theV arcuately radial openings of theapertured slotsV 'I1 and I8 thus providing a lock for the cap Vwhen closed. The position of the Vdepending prongs 29, 39 is indicated in dotted outline to the right and left of the apertured opening I'I, showing thepositionrof the prongs when in 'locked engagement. The turned over portionsY I5 and I6 Yhave bearing surfaces. provided Yat the extreme neck I ll.

@Wing to the; design and construction of the 1 The slots I1, VI8 also provide at their V.narrow stay portions 33 and 34 of the notched The bent over shell-formed tubular body I2, a Yneck portion isY thusV formed Yhaving arportion WhichV may be of anysuitable length.V The apertured neck II of the tube Vcan be made very short becausethe shell-formed tubular .body vI2 isV formed in'such away that the turned over portions I5 and I8 at 31 and 35 bear upon the external surface of the Y any of its advantages.
